Both (*SPOILERS* in the link) Dark Horse and (*SPOILERS* in the link) IDW have confirmed that the Angel series is returning to Dark Horse. From the IDW link, it doesn't sound as if IDW was too pleased at the way Dark Horse announced the change but it at least sounds like the transition will be coordinated, even smooth, if all goes to plan. It also sounds like all the new IDW-generated characters will make the move over to Dark Horse and that Joss will be involved in all of this. Let's hope there's not too much retconning to make everything fit!
